I bought this to carry my clothes, a camera, & my cell phone on a river tubing trip. I was nervous about electronics & potential water seepage, so I put my phone and camera inside of two Ziploc bags and put those bags inside of this dry bag. The Ziploc bags were an unnecessary precaution. I spend 4 hours on the river, during which time this bag became submerged repeatedly. At the end of the trip, not a single drop of water had found its way inside. My clothes were completely dry and electronics were safe and dry. Before I purchased this item, I looked at a lot of dry bags and read several reviews before settling on this one. The fact that it came with a carrying strap was ultimately what made me decide on this one. The strap was great and I was able to wear the dry bag across my body, instead of tying it to the tube, and that made me feel more comfortable. This one is still in great shape, but when it comes time to replace it, I would definitely buy it again.Took this on a 3 day sailing trip to the Channel Islands and seems fine, though it hasn't gotten wet yet. You simply roll the bag down and clip it. There's no velcro or other fastener, so we'll see if it's actually a dry bag. I'll upgrade to five stars if it stays dry.DRY BAG: kept camera and all dry on boating trip, thick, does have a bit of weight to it, likely because of its excellent quality and build, tough. Also used for beach excursions while on a cruise, excellent again ! Top folds so if you dont need it to be 24", keep folding and it goes to about 12-15 inches, making it much less bulky and easy to carry when you dont have it full. We had camera, fins, mask, snorkeling vest and two towels in it.a little larger than I expected, but had no idea how big it really was. I can make it 'smaller' by rolling it. Great price compared to other bags I researched. This has the handle and shoulder strap which makes it a good seller too.Goog bag!!La probe, no me meti al agua con ella, sin embargo le cayo una buena cantidad de agua encima, se alcanzo a filtrar un poco pero nada grave, solo algunos mililitros, tengan en cuenta que solo se cierra dandole vuelta y con el broche, en mi opinion tal vez tendria que haberla cerrado con mas vueltas o un poco mas apretao, pero en comparacion a los que llevaban mochilas normales y bolsas de plastico esta no le paso nada y las otras empapadas, lo que llevaba quedo seco y mis cosas electronicas las heche adentro, de otra bosa con cierre tipo ziploc.Also der Sack ist optisch ok, spritzwasser und schwimmend hält er bestimmt dicht. Bei einer Bootskenterung allerdings nicht, es waren bei mir etwa 5l wasser drin. Zusätzlich das was die Klamotten aufgesogen haben. Schade.Farbe ist nicht ganz dem Bild entsprechend. Geht mehr ins beige. Schade. Das Material ist sehr steif, wenn man bis zum Griff gerollt hat, kann man die Enden, zum zusammen klippen, schwer biegen. Ich habe bereits zwei Dry bags, die nicht so klobig sind.Preis Leistung passt bei diesem Produkt. Schöner stabiler Stoff. Gut verarbeitet. Sicher kein High-End-Produkt, aber zum Schlauchbootfahren oder ähnliches ist er super. Wasserdicht würde ich nicht unterschreiben. Oben kann Wasser reinlaufen. Der Rest ist dicht.La parte de atrás de la bolsa no tiene costuras, está pegada con algún tipo de goma y la mía tenía un agujero de unos cinco centímetros en esta parte. Los acabados son regulares, lo cual no me importaría si la bolsa fuera funcional. No recomiendo este producto.
